Here it is again....need target statement

Been at this for hours. I feel like crying!

app.js 
let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
});

section.addEventListener('click', e => {
    if (e.target.tagName == 'INPUT') {   
      e.target.style.backgroundColor =  'blue';      


    }
});
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>JavaScript and the DOM</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <section>

You have the right idea but now you have 2 event listeners on the section element. The challenge is to add a conditon to the first EventListener and only target the input element.

If you cut out the if statement in your last EventListener and use that in the one provided you should be able to finish the challenge.

Like so:

let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if (event.target.tagName == 'INPUT') {
    e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
});
